1. Preheat oven to 475 degrees. Toss panko with herbs and 1 tablespoon oil.
2. Place salmon (skin down) on parchment-lined baking sheet. Spread evenly with mustard; season
with salt and pepper. Sprinkle with reserved panko mixture, patting
gently. Scatter lemons around salmon and drizzle them with oil.
3. Roast salmon until it flakes easily, 18 to 20 minutes. With a large spatula, loosen it from skin (which should stick to parchment).
Transfer fish to platter and garnish with roasted lemons.
